How to Track Push notifications opens data

Hi Team, 

We are currently facing an issue where we want to track the impressions, which i would think the recipient or contact received the push message from FCM.

Our App developers have followed the below document and called the notifRecieve function while calling onMessageReceived function

And also in the general diagram of the push notification enablement we see that the imppressions are trackable in the tracking data, below is the reference doc for the same.

We also checked in the trackinglogAppRcp table , but we do not have any enums association for that, but in broadlogAppRcp table we have the recieved on mobile enum available. Now post the above function is called we do not see the data in either of the tables (trackinglogAppRcp or broadlogAppRcp). So wanted to know how can we get the impressions data coming in for the push notifications sent to the customers from FCM.
